worm}; TEXAS ,IN'SEC'I. EX'IEBMINATOR Application filed. May 10,

. This invention relates to insect exterminators, and its general object is to provide a machine to be propelled and operated in a field of vegetation, such as cotton, and between the rows thereof to remove insects and the like from the plants and cause them to'be dis-" posed in the path of burners of the machine whereby the insects. and the like will be destroyed by streams of burning fuel from the 0 burners and without injury to the plants by heat or otherwise.

Another object of the invention is to provide an insect exterminator with burner casings that include insulating material so'that the casings will hold heat and-prevent the same from injuring the plants, yet the casings are shaped to direct flame and heat where it will do the most good.

A further object of the invention is to provide an insect exterminator that includes burner casings, each having a plurality of individually controlled burners, whereby one or more burners can be used as desired.

A still further object of the invention is to provide an exterminator of the character set forth that is light in weight, simple in construction, inexpensive to manufacture, and iseflicient in operation and-service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts,

.to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out inthe appended claim.

In describing our invention in detail, reference will be had to the accompanying drawings wherein like characters denote llke or corresponding parts throughout the several views, and in'w ich Figure 1 is a side elevation of a' machine constructed in accordance with our invention.

Figure 2 is a top plan view thereof. Figure 3 is a rear elevation. Figure 4 is an approximately sectional vlew showing the position of one of the burners with respect thereto.

\ Referring to the drawings in detail, the

reference numeral 1 indicates an arched axle taken thru one of the burner casings and which as best shown in Figure 3 is substan- 1929. Serial ms. abadso.

tially U-shaped and terminates at its ends to providespindles to receive the groundvengaging wheels 2. Secured to the arched axle and at the opposite ends thereof are brackets 3 terminating at their upper ends in notched guadrants 4 for a purpose which will be later escribed, and fixed to these brackets upon the inner sides thereof are the rear ends of parallel portions 5 of a frame which has its forward ends bent to provide converging por-' tions 6 which terminate in parallel ears 7 as best shown in Figure 2. These ears receive the rear end of the tongue 8 and are secured thereto'thru the medium of bolts or the like as shown.

Secured adjacent to the rear ends of theparallel portions 5 are upwardly inclined supporting bars 9 which have their upper ends disposed together for the purpose of supporting a seat 10, and the bars 9 also exof disposing the seat accordingly.

Secured to the inner side of the tongue adjacent its rear end is a strip 11 that extends a considerable distance upon the opposite sides of the tongue, and depending from the strip in spaced parallel relation with respect to each other, and secured thereto accordingly is a plurality of chains 12 which are primarily adapted forengagementwith the plants to remove insects and the like therefrom when the machine is travelling thru a field of vegetation. The machine may be propelled by any well known means such-as draft animals, a tractor orthe like, and this means may be associated with the tongue in any well known manner. v

Brace bars 13 are provided for the frame, and these bars have their upper ends fixed t0 the parallel portions 5 and the lower ends secured to the spindles as best shown in Figure 2. The burner casings which are indicated by the reference numeral 14 are preferably made up of two sheets of metal, with a sheet of asbestos between the same so that the casings will retain their heat for a maximum period of time, and these casings which are arranged in pairs as best shown in Figure 2, are provided with inwardly inclined top walls 15,

70 tend rearwardly of the frame for the purpose straightv rear walls 16, outwardly inclined outer walls 17 which are relatively wide as shown in Figure 4, and extremely narrow inner walls 18, due to the shape of the casings and the top walls thereof. The upward walls 19 of the burner casings converge toward each other and terminate man edge 20 as shown in Figure 1. The casings aredisposed so that their inner walls 18 are arranged in spaced relation with respect to each other as best shown in Figure 3, and the outer walls are provided with openings 21 arranged in parallel relation with respect to each other. The

casings are adj ustably supported with respect to the frame and for this purpose we provide downwardly and inwardly extending arms 22,

that have their upper ends secured to the outer sides of the parallel portions 5 and the lower ends which are disposed inparallelism,

have secured thereto the forward ends of.

rearwardly extending supporting bars 23, and the lower ends of the arms 22 are fixed to the casings as at 24. f

The arms 22 as above set forth are secured to the forward ends of the casings, While secured to the rear ends of the casings isa hook bracket 25 which receives one of the end links .of chains 26, and the upper end links of the 1 chains 26 are secured to links-27 that are pro- .vided with a plurality of openings for'the purpose of being adjustably-secured to the rear end of the rearwardly extending: supporting bars 23 thru the medium of bolt and nut connections passing thruany one of the openings of the links, as suggested in Figure 1 1. By this construction, it will be ap arent thatthe rear ends of the casings can e adjusted with respect to the ground, and in order to raise and lower the casings, we provide rods'28-thathave their lower ends se-f cured to the extending bars 23 adjacent the forward ends thereof, and their upper ends are received by coil springs 29 which are in turn secured to the lower ends of arms 30 that are formed with bearingssurrounding and mounted for rotation on stub shafts 31 formed with the notched quadrants '4 as shown in Figure 1. These bearings also have formed therewith levers 32 that terminate in handles f and the coils have formed therewith and risand have secured adjacent the handle ends thereof gripping levers 33 which controllatching bolts to e received inthe notches of the notched uadrants whereb the casings may be raise and lowered an held in any adjusted position desired.

Arranged in each casing and adjacent each opening therein are burner coils 34 which have formed therewith and extending thru, the openings sections 35 with burner nozzles The burner. nozzles are 36 secured thereto. 7 controlled by valyes having finger handles 37,

each casing as shown in Figure 2, and these pipe sections 39 have their rear ends closed,

' while their forward ends are upwardly directed to receive the lower ends of tubes 40 that have their upper ends connected with valves 41 which are connected with a tank.

The tank 42 is supported by the frame and secured thereto by bands'43 carried by upright brackets 44, and the tank 42 is provided with a filling spout, and a pum 45 whereby air may be supplied thereto as W1 1 be apparent. v

From the above description and disclosure of the drawings, it will'be obvious that we have provided an exterminator for killing insects and the like, and the exterminatorcan be used in fields of vegetation" and between the rows thereof to remove the insects from the plants, and thence destroy them by streams of burning fuel from the burners. Due to the shape of the casings and the arrangement thereof, it will be apparent that the heat willnot only be confined where it will do most good, but the heat will in no way affeet the plants.

The machine will also act to burn weeds,

small vegetation and the like betweentherows, and with its insect destroying properties, the

plants'will grow without interference from It is thought from the foregoin description thatthe advantages and novel atures of our invention will be readily apparent.

We desire it to be understood that we may make changes in the construction, and in the combination and arrangement of the severalv parts, provided that such changes fall within the scope of the-appended claim.
